what is y=1/2x -4

Question

what is y=1/2x -4

Answer 1

You can just plug in numbers and graph the corresponding points.

 

y=1/2x-4

 

when x=0, y=1/2(0)-4, so y=-4

when x=1, y=1/2(1)-4, so y=-3.5

when x=2, y=1/2(2)-4, so y=-3

when x=4, y=1/2(4)-4, so y=-2

when x=8, y=1/2(8)-4, so y=0

 

So far we have (0,-4); (1,-3.5); (2,-3); (4, -2); (8,0). Plot these points and connect them with a line extending indefinitely, and you have y=1/2x-4.
